WebThe cardiac output of trained endurance athletes may increase from 5 to 6 L/min at rest to up to 40 L/min during maximal exercise. 73 The heart adapts to this volume load with an increase in internal diameter. Blood pressure also increases during endurance exercise, although to a lesser extent than during strength training. WebThe small-to-modest increase in cardiac output during resistance exercise is the result of a modest increase in heart rate and an unchanged or decreased stroke volume. The acute cardiovascular responses to resistance exercise just described are in stark contrast to those seen during aerobic exercise. Cardiac output increases dramatically during ...
